WOOL-WASHING BOWL.

Patented Feb. 18,1908.

Application filed June 10. 1907- ,Serial No. 3'78|190.

To all whom it may concern:

Be it known that I, FREDERICK G. SAR- GENT, a citizen of the United States, residing at Westford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Wool-Washing Bowl, of which the following is a specification.

This invention relates to that class of wool washing machines in which a bowl is em ployed, preferably comprising a plurality of bottoms having one or more slanting sides or walls. The usual construction of these washing bowls is to have the slanting bottoms of such a shallow nature that they are sup ported by the usual legs or other supports at a short distance above the floor. It has been found that it is desirable to have these bottoms of such form that they can be deeper,

one reason being that the sediment which collects will more easily descend to the valve which is located at the bottom, and which is opened for cleaning out the same. While it is not practicable to raise the body of the bowl above the height at which it is usually placed, the bottoms can be extended below the floor into pits or the like. This is hardly practicable, however, with the ordinary construction of bowl, for by simply making the inclination greater, the bowl bottoms are necessarily made so large and heavy that there is difliculty about shipping them.

It would be very inconvenient and in fact almost impossible to ship one of these bowls with one of the deep bottoms attached to the bowl, as all these machines are shipped with wooden shoes fastened to the feet of the bowls and it will be obvious that if these bottoms were left complete on the bowls, they would be raised up so high that it would be almost impossible to boX the machine. so that it could conveniently be placed on the cars or transferred therefrom. Now, as these machines are all set up in the shop with their, crossshafts and the like all lined up, it is necessary to have these bottoms in the machines when they are constructed and that would be impracticable with such deep bottoms.

The principal object of the present invention is to provide a construction of such a naturethat the parts can be shipped in a convenient. manner, and the weight of the entire device can be materially lessened even when the advantage of the more sharply sloping bottoms is secured.

Reference is to be had to the accompanying drawings, in which Figure 1 is a side elevation of a portion of a wool washing machine with one form of my invention applied thereto. Fig. 2 is a longitudinal sectional view of the same, and Fig.3 is a transverse sectional view through the center of one of the sections of the bowl.

The invention is shown as being applied to a wool washing machine, in which the bowl is made in sections 10, each being provided with a bottom having four slanting walls. It is to be understood, however, that the invention can be applied to bowls which are not made sectional, and to those in which some or all of the walls are not at an inclination. In this form of bowl a screen 11 extends from one end to the other, the bottoms being located below the screen to receive the sediment coming from the wool thereon. In the present case these bottoms consist of two parts 12 and 13. It will be observed that the slant of thewalls in both parts is the same, and that there is a continuous straight handling and enable the advantage of the sharply sloping bottom to be effectively applied in practice, and for the additional reason that the-weight of the whole device may be materially reduced. This latter effect is produced on account of the fact that the section 12 constitutes a support for the section 13, and consequently,the section 13 can be made of lighter and thinner material than the section 12, as indicated.

In order to secure the two sections together, the section 12 is provided with a hori zontal flange 17 at the bottom, and the section 13 with a flange 18 at the top. These flanges register with each other, and are secured together by means of bolts 19 or in any other desired way.

The upper section is also provided with a vertical flange 20 which is secured to the walls of the washing machine in any ordinary manner. It will be seen that in constructing the bottoms of the bowls in this manner they can be taken apart for shipping, nested together, and the bottom parts may be made lighter than would be the case if the whole of the bottom were in one piece.

From what has been stated it will be seen that by having the bottoms made in halves, as specified, the upper half only is placed in the machine when it is set up for shipping and therefore, the machine is all complete with all its shafting lined up and mounted in the upper half. Then when placed in the mill, the lower bottoms are first placed in the space below the floor and the machine is then placed over this space. The lower halves can then easily be lifted up and fastened to the bottoms already on the bowl. This makes the deep bottom a practical one to build which it would not be without the horizontal division specified. It will be seen that if this lower bottom had to be made in one piece with the rest of the bottom, the floor for settingup the same in the manufacturers establishment would have to be constructed with a trench underneath for that purpose, also in shipping, this bottom would have to be taken out again which would throw the bowl sides out of line and consequently, nullify all the labor in lining up the shafting, going through or connecting with, the bowl.-

It will be seen, therefore, that by this simple improvement, a great advantage is obtained in the manufacture of these bowls.

While I have illustrated and described a particular form of the invention, I am aware that modifications may be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore Ido not wish to be limited to the particular form shown, but

What I do claim is 1- 1. A woolwashing machine having a bowl provided with a bottom in two parts, the upper part having afiange around its lower end, and the other part a flange around its upper end, said flanges being secured together, whereby the upper part supports the lower part, and the lower part may be removed when the machine is to be shipped or moved.

2. A wool washing machine having a bowl consisting of sections, each provided with a bottom comprising an upper part constituting a support, and a lower removable part depending therefrom, the inner walls of said upper and lower parts being continuous .with respect to each other.

3. A wool washing machine having a bowl provided with a bottom consisting of two parts, an upper part constituting a support, and a lower part depending therefrom, said upper and lower parts having registering flanges securedtogether, the upper part being formed of metal having a greater cross section than the lower part, whereby the lower part is of lighter character, the walls of the upper and lower part being'continuous with respect to each other and on substantially the same inclination, said upper part being secured to the walls of the bowl of the washer.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
